My invention relates to a woven, endless feed ribbon of the type adapted for use, for instance,

on laundry machines.

An important object of the invention is to provide a feed belt which will be comparatively nonstretchable or inextensible and capable of manufacture at minimum cost.

According to the invention, the improved ribbon has a casing preferably of cotton fabric folded upon itself at a distance approximately one fourth of its width from each of its opposite longitudinal edges and again folded upon itself ap-- proximately midway between its longitudinal edges into four plies to form a casing, a core of comparatively non-stretchable fabric, such as jute, of approximately the same width as that of said plies, interposed between the second and third plies of cotton fabric, and a multiplicity of relatively close, longitudinally extending, parallel rows of stitching securing the core and casing together.

Another object is to provide a ribbon structure wherein the initially free edges of the sheet from which the casing is formed are locatedinteriorly of thecasing and out of the same plane so that they cannot undesirably bunch or overlap, especially while the longitudinal stitches are being made, which would result in a dissimilar or uneven cross section.

Various additional objects and advantages will become apparent from a consideration of. the following description taken in connection with the accompanying drawing illustrating one exemplary embodiment of the invention.

In said drawing:

Figure 1 is a perspective view of the improved feed ribbon;

Figure 2 is a fragmentary plan view of the ribbon in its initial stage of manufacture;

Figure 3 is a fragmentary plan view of the ribbon in an intermediate stage of manufacture;

Figure 4 is a fragmentary plan view of the ribbon, and V Figure 5 is a cross-sectional view takenon the line 55 of Figure 4.

Referring in detail to the drawing, wherein like reference characters designate like or corresponding parts in the different views, the improved feed ribbon is generally designated 9 and primarily consists of a sheet 10, preferably of cotton, although an equivalent textile fabric may be used. The said sheet 10 is folded upon itself from its opposite side edges along fold lines 11 and 12 (Fig. 2) each located approximately one fourth of the distance from one longitudinal edge of the sheet to produce layers 13 and 14 as shown in Fig. 3. At this stage, a core 15, of a width slightly less than the width of the layers 13 and 14, is inserted between the layers 13 and 14. Said core 15 is a single layer or band formed preferably of jute fabric since this material is comparatively nonstretchable and is inexpensive. As best shown in Figs. 3 and 4, the longitudinal threads of the jute core 15 are parallel to the side edges of the ribbon. In lieu of the jute fabric, the core 15 might, at greater expense, be made of a fabric formed of animal fiber or other vegetable fiber which is non stretchable as compared with cotton.

After the core 15 has been inserted between the layers 13 and 14, the sheet 10 is again folded along a central line 16, thus producing intermediate layers 13 and 14 with the core 15 therebetween and outer layers 17 and 18. Thus the initially free edges 19 of the cotton fabric 10 are not marginally exposed but are located within the casing formed by such fabric and adjacent the central fold line 16 which constitutes one edge of the ribbon.

In order to secure the layers 13, 14, 17 and 18 and core 15 together and also to assist in preventing the undue stretching of the ribbon, a multiplicity of relatively close rows or lines of stitching, as at 21, are made through all of the layers and the core. Preferably these lines of stitching extend longitudinally of the casing, as shown. In practice, the stitching thread is preferably of linen and the lines of stitches 21 may be one-sixteenth of an inch or even a less distance apart.

Since all of the layers 13, 14, 17 and 18 and the core 15 are of approximately the same width, the edges 19 of the folded cotton sheet lie in different planes and hence there is no possibility of their becoming bunched, especially during stitching, in such a way as to result in unevenness in the thickness of the ribbon and in weakened portions therein.

Various changes may be made and scope of the invention.

I claim as my invention:

A woven endless feed ribbon comprising an endless sheet of cotton fabric arranged in four coextensive, superposed layers, the initially free edge portions of the sheet constituting the innermost layers, a core of jute fabric coextensive with each layer disposed between two of the layers, all longitudinal edges of the layers and core thereby being located at the longitudinal edges of the rib- .bon, said core having longitudinal threads in substantial parallelism with the longitudinal edges of the ribbon, and a multiplicity of relatively close rows of stitching substantially parallel to said longitudinal threads securing the layers and core together.
